Will the stock muffler hurt the horsepower?

I think i have a set that were good on a wrecked truck ! I may try them . Then run a datalog

Truck was to loud and had to hear the neighbors cry.

Just put on stock muffler. thats it still has the headers .

I had to change the exhaust and go back with stock style and the numbers were crazy on this run i hope that doesnt mess it up .

Its running good it does the return to idle like you spoke of .

And I really didn't let truck warm up before i do the datalogs.

02 are just at bottom of long tubes and are new . Maybe there not good ones or something . I had just replaced the passenger side

oh yea it runs good when you give it gas . And seems ike it has a lot more power or get up and go.
